Use existing GRASS mapset (or create a new one) with matching projection settings

Now you have to transfer the SHAPE file from QGIS to GRASS using Toolbox -> File management -> Import into GRASS -> Import vector into
GRASS -> Import vector into GRASS from QGIS view (v.in.ogr.qgis). Some
topological problems may be reported depending on the quality of your
SHAPE file.

These topological problems we can fix now in GRASS via toolbox using the topology tools: Vector -> Develop map -> Toolset for
cleaning topology of vector map -> v.clean.break. Define a threshold
in map units (for example 0.5 [m] or likewise). Analyse the printed
report, probably the threshold needs to be adjusted or a different
topology cleanup tool to be used. Click then on view output to show
the result as map.

Does the new Topology Checker can clean topology errors or manage topology with rules similarly to ArcGIS 10? Is there a segment snapper tool like in ArcGIS 10? Thank you.

Has this plugin already been released? If yes, where can I find it?
